There was no 1:1 relation between the playing time of the music and the counter. The relationship between counter value and time was definitely non-linear. I programmed my HP11 tot convert between the two. For converting counter value to time I had to add a sinus-like function (doing one cycle per side-length 45 minutes) to a straight line. If anyone is interested I'll post it. Particularly useful for owners of a working early '80s Philips cassette player. Some other non-math applications: * games; Mastermind, Mahjong-scores (both posted), Blackjack. * dice (like many others) * medical calculations: - multiple category-counter (for counting white bloodcells by type) - expected lung volumes for a given sex, age & height, - blood-gas analysis - body surface area - glomerular filtration rate (eGFR/MDRD) HP 33E, HP 11C, HP 48 SX, HP 35S |
